Part 3 Flashcards
When the hemoglobin in your blood is fully saturated the partial pressure in your plasma is about
100mmHg
The normal partial pressure of oxygen in your body is?
40 mmHg
What two things lower your hemoglobin’s affinity (need) for oxygen
Heat and CO2
If you are having inflammation what does your hemoglobin in your blood?
Empties the oxygen it is holding onto and dumps those oxygen cells to help with the inflammation (this lowers your oxygen supply)
The spike of CO2 that can be released by your active muscle tissues make your blood more?
Acidic
When CO2 dissolves in water(plasma) it forms
Carbonic acid
Carbonic acid future breaks down into
bicarbonate and hydrogen ions
When hyperventilating and your CO2 levels in your blood drops what happens to your Ph level?
Your pH rises
A high pH and hyperventilation causes what to your veins
Vasoconstriction
What mask is best for treating hyperventilation
A nonrebreather
What is the membrane that covers the lungs
The lung Pleura
What part of the lung is the entrance for air from the trachea
The Hilum
The apex of the heart is directed in the cardiac notch which is in what part of the left lung
The anterior lingula of the left lung
The right lung has how many fissures and name them
2 - Horizontal fissure and Oblique fissure
The left lung has which fissure
Oblique fissure
Wha are the 3 lobes of the right lung
Superior, Middle, and Inferior
How many segments are in the right lung
10 segments
How many segments are in the left lung
8 segments
What are the two layers of the pleura that surround the lung
The Visceral pleura and the parietal pleura
What is in-between the Visceral pleura and the parietal pleura layers
The pleural cavity
The pleural cavity contains what
Fluid for lubrication of the lung
What is the area between the lungs and the spine
The mediastinum
